Catalyst performance is paramount in producing high-value lubricants. Refiners trust catalysts from CriterionCatalysts & Technologies (Criterion) to deliver high yieldsof top-quality base oils. Consequently, our products areto be found in lubricant plants across the world.

Lubricant base oils are manufactured from vacuum gas oils and

high-quality deasphalted oils. These feedstocks are improved

through several processing steps, including lube hydrocrackingdewaxing/isomerisation, hydrofinishing and hydrotreating.

Criterion has a proven record of delivering high yields and

enhanced quality lubricant base oils through its range of

high-performance catalysts for use in these key processes.

LUBE HYDROCRACKINGLube hydrocrackingimproves the yield and quality oflubricating oils by increasing their viscosity index, reducingtheir aromatic content and removing sulphur and nitrogen.Different combinations of our LH catalysts, which are based on

CENTINEL, CENTINEL Gold and CENTERA technologies, areused to meet the needs of our lube hydrocracking customers.Refiners are increasingly following this processing step beforefurther enhancement in catalytic dewaxing/isomerisation and

high-severity saturation units.

CATALYTIC DEWAXING/ISOMERISATION AND SATURATIONCatalytic dewaxing/isomerisationproduces high yields

of superior-quality base oils. Gas to liquids (GTL) processes

create very pure unbranched hydrocarbon chains with virtually no

aromatic content or unwanted heteroatoms. These waxes require

isomerisation for conversion into lubricant base oils. Catalytic

dewaxing using commercial Criterion catalysts is our most

facility in Ras Laffan, Qatar.

Saturationcatalysts give catalytically dewaxed/isomerised

products excellent final properties. Noble metal catalyst C-654

has been used for over a decade to produce highly saturated

lubricants, including the final production step for medicinal white

oils. C-684, our latest noble metal saturation catalyst, offersadditional activity and stability in the presence of increased levels

of sulphur and hydrogen sulphide.

OUR NEW FAMILY OF CATALYSTS BASED ON CENTERATECHNOLOGY IS SETTING NEWPERFORMANCE STANDARDS.

HYDROFINISHING ANDHYDROTREATINGHydrofinishingcatalysts have been improving the appearance

and properties of lubricating oils for almost 50 years. They

enhance the colour, remove impurities such as sulphur and improve

stability and additive response. At Criterion, we have a long

history of producing highly effective hydrofinishing catalysts, which

are based on the proven performance of our NiMo ASCENT

DN-3551 catalyst and our CENTINEL family of catalysts.

For more severe hydrotreating, CENTINEL Gold technology

has a strong record of providing excellent performance, and now,

our new family of catalysts based on CENTERA technology is

setting new performance levels.

TECHNOLOGY LEADERSHIPCriterion has an impressive history of catalyst innovations; we

introduced our high-performance lubricant catalysts C-424 and

C-454 more than 25 years ago. Since then, we have constantlypushed lubricant catalyst technologies to increase yields and

enhance base oil quality.
